This after the Cape Argus reported on Wednesday that the summit had been called off, citing unnamed independent sources.
Nobel peace prize winner Jody Williams told Agence France-Presse (AFP) on Wednesday that the summit had been cancelled because “enough Nobel laureates refused to go”.
Last month, 14 Nobel laureates wrote to President Jacob Zuma asking that a South African travel visa be granted to the Dalai Lama.
This was the third time in five years he could not secure a visa to enter South Africa.
At the time the international relations department said the Dalai Lama’s visa application was a closed matter, and that he had cancelled his trip.
Archbishop Desmond Tutu on Wednesday criticised the government for allegedly refusing a visa to the Tibetan spiritual leader.
“I am ashamed to call this lickspittle bunch my government,” he said in a statement.
